STREET-SPRINKLER.

Specification of Letters Patent.

Patented Dec. 11, 1906.

To all whom it may concern.-

Be it known that I, JosnPH B. HALL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Street-Sprinklers, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to street-sprinklers, and has particularly to dowith the construction and operation of sprinkler-heads designed for useon sprinkling carts or cars.

The objects of my invention are to provide a new and improvedconstruction of sprinkler-head containing in itself all the partsnecessary to fulfil every requiiement- 'L. a, to start and stop the flowof water, to discharge the water at either side of the sprinkler-head,and to regulate the quantity discharged at either side; also, to providean improved construction whereby every operation of adjustment andcontrol of the sprinkler-h1ead may be effected from the platform withoutinconvenience to the operator. I accomplish these objects as hereinafterdescribed and as illustrated in the drawings.

What I regard as new is set forth in theclaims.

In the accompanying drawings, Figure 1 is a partial side elevation ofthe platform of a car or cart, showing my improved sprinklerhead inposition, together with the operating mechanism therefor. Fig. 2 is anend view of the parts shown in Fig. 1. Fig. 3 1s a longitudinal verticalsection of the spr nklerhead. Fig. 4 is an end view of the sprnklerhead. Fig. 5 is an end view of the sprmklerhead, the removablemember thereof being removed, certain parts being insection and Fig. 6is a side elevation of said removable member or head.

Referring to the drawings, 10 indlcates the platform of the car, and 11the sprinklerhead, which is secured by an upwardly-proj ecting lug 12 toone of the SlllS 13 of the car. While this construction is preferred,the sprinkler-head may, however, be secured to the car or cart in anyother suitable manner.

14 indicates the main supply-pipe, through which the water is suppliedto the sprinklerhead.

The construction of the sprinkler-head is I best shown in Fig. 3, froman inspection of which it will be seen that the pipe 14 communicateswith a chamber 15, which may be termed the main-valve chamber.- Thecasing or shell of the sprinkler-head is made up of three members, twoof which are rigidly secured together, the third member being movabletoward and from the intermediate member for the purpose of controllingthe area of the discharge passages or slots, as hereinafter described.

16 17 indicate the stationary members, and 18 the movable member orhead. As shown in Fig. 3, the member 17 is intermediately arranged andis firmly secured to the end member 16 by polts 19, which pass throughperipheral flanges 20 21, carried by the members 16 17, respectively. Apackingring 22 is provided between said flanges to prevent leakage. Theintermediate member 17 is also provided with an internallyprojectingflange 23, which forms a valveseat for the main valve of thesprinklerhead, as will be hereinafter described.

The construction of the movable member or head 18 is best shown in Figs.3 and 6. From an inspection of the latter figure it will be seen thatthe inner edge of the head 18 is partly cut down, providing a projectingstrip 24. Said strip extends through an arc of about one hundred degreesand fits into a corresponding recess in the outer edge of theintermediate member 17, as indicated in Fig. 3. The outer edge 25 of theprojecting portion 24 of the head 18, together with the opposing edge ofthe intermediate member 17, forms one of the slots through which wateris dischargedfrom the sprinkler-head, while the edge 26 of the mainportion of the head 18, together with the opposing edge portion of theintermediate member 17 forms another slot for the discharge of water.Obviously by adjusting the head 18 toward and from the intermediatemember 17 the width of said slots may be adjusted at pleasure. The head18 is adjustably supported by means of a sleeve 27, which is formedintegral with the head 18 and is concentric therewith, said sleeve beingmounted upon a tubular support 28, carried by a bracket 29, which issecured to the outer surface of the flange 21 by means of the bolts 19,as shown in Fig. 3. Said bracket extends over the members 17 18 to apoint a sufficient distance IOC beyond the outer end of the sleeve 27 topermit said sleeve to be adjusted freely thereupon. By this constructionthe head 18 may readily be moved toward and from the intermediate member17, and the area of the discharge-slots thereby regulated. For thepurpose of adjusting the head 18 a lever 30 is provided, which ispivoted at 31 upon the bracket 29 and is provided with a fork 32, whichfits in an annular recess 33 in the sleeve 27, as shown in Fig. 3. Theupper end of said lever 30 is provided with an eye 34, which fits upon areduced portion of a screwshaft 35, mounted in a threaded support 36,which is secured in any suitable way to one of the sills 13, so that byrotating the shaft 35 it may be slowly moved up and down,correspondingly rocking the lever 30 and adjusting the head 18. Toprevent leakage between the sleeve 27 and the support 28, an annularpacking-strip 37 is provided, which is held in place by a ring 39,secured by screws 40 in the inner end of the sleeve 27 adjacent to thesupport 28, as shown in Fig. 3. j

41 indicates a regulating-valve by which the operative length of theslotat one side of the sprinkler-head may be adjusted. 42 indicates asimilar valve for the other slot. As shown in Figs. 3 and 5, said valves41 and 42 are segmental in form, being curved to fit the interiorsurface of the sprinkler-head, so as to lie closely over theirrespective slots. Strips 43, of leather or other suitable material, areprovided between the valves 41 42 and the interior surface of thesprinkler-head, so as to insure water-tight contact. The valve 42 iscarried at the inner end of a tubular shaft 44, fitting closely in thesupport 28, through which it extends, as shown in Fig. 3. The shaft 44is provided near its inner end with a peripheral flange 45, which bearsagainst the inner edge of the support 28, thereby preventing said shaft44 from being forced out of the sprinkler-head. ried at the inner end ofa tubular shaft 46, which fits closely inside of the shaft 44, throughwhich it extends, as shown in Fig. 3. The shaft 46 is provided near itsinner end with a peripheral flange 47, which bears against the inner endof the shaft 44 and serves the same purpose as the flange 45.

48 indicates an arm fixedly secured upon the outer end of the shaft 44for rocking said shaft to adjust the valve 42. 49 indicates a similararmsecured upon the outer end of the shaft 46 for rocking said shaft toadjust the valve 41. By rocking either of said arms the correspondingvalve may be .adjusted' to vary the operative length of thecorresponding slot, thereby controlling the length of the streamdischarged at either sideof the sprinkler-head. As best shown in Fig. 5,the valves 41 42 are connected with their respective shafts by pins 50,the outer ends of which fit loosely in The valve 41 is car-.

bosses 51 in the inner surfaces of said valves, and in order to hold thevalves closely in contact with the inner surface of the sprinklerheadsprings 52 are provided, which fit upon said pins, the outer ends ofsaid springs bearing against the bosses 51, while their inner ends bearagainst collars 53, carried by the pins, as shown in Fig. 5. The valvesare thus held closely, though yieldingly, in contact with the innersurface of the sprinklerhead.

54 indicates an operating-bar which is connected to the arm 49 andextends up to the platform of the car, where it is provided with ahandle 55, by which it may be conveniently operated. By adjusting thebar 54 the arm 49 may be rocked to adjust'the regulating-valve 41.

56 57 indicate pins carried by the bar 54 to limit its movement ineither direction, one of said pins being above and the other below theplatform 10, as shown in Fig. 2.

58 indicates a lever mounted on a pivot 59 and connected with the arm 48for adjusting the regulating-valve 42. As best shown in Fig. 1, thelower end of the lever 58 extends through a slot in a block 60, mountedon trunnions between the outer ends of the arm 48, which is bifurcated,as shown in Fig. 1. Consequently by rocking the lever 58 in eitherdirection the valve 42 may be correspondingly adjusted.

61 indicates the stem of the main valve. As shown in Fig. 3, thevalve-stem 61 is fitted in the tubular shaft 46, extending through saidshaft from end to end. At its inner end the stem 61 carries the .mainvalve 62 and a disk 63, of leather, which is placed between said valveand the seat 23. Nuts 64 65 are provided on the stem 61 for adjustingthe valve 62 and disk 63, as may be desired. The outer end of the stem61 is provided with a nut 66 to limit its inward movement, as shown inFigs. 1 and 3. 67 indicates a treadle for operating the main valve 62.As shown in Fig. 1, said treadle projects through the platform 10, itslower end being connected by a connecting-link 68 with a rockshaft 69,pivoted at its ends between hangers 71, secured to one of the sills 13,as shown in Fig. 2. The rock-shaft 69 is provided with anupwardly-projecting lug 70, with which the outer end of the valve-stem61 is connected, as best shown in Figs. 1 and 2. By this constructionwhen the treadle 67 is depressed the shaft 69 is rocked to throw the lug70 inward toward the sprinklerhead, thereby opening the main valve.Upward movement of the treadle closes the main valve. In order to closethe main valve automatically, a spring 72 is provided upon the stem ofthe treadle 67, as best shown in Fig. 2 and in dotted lines in Fig. 1..As shown in Fig. 2, the lower end of the spring is supported by a hanger73, secured to the latform its u er end bearin a ainst a P 1 g g collar7 4, carried y the treadle 67 and held in position by a pin 75. Thespring 72 is a compression-spring and acts to raise the tre'adle 67 whendepressed, and consequently operates to close the main valve 62.

In order to hold the main valve open when desired, the treadle 67 isprovided with a notch 76, adapted to receive a tooth 77, carried by aspring-plate 78, when the treadle 67 is depressed sufficiently. Thetreadle may be released and the main valve closed by simply pressing itaway from the plate 78 far enough to disengage the tooth 77. Instead ofusing this form of locking device any other equivalent means may beemployed to lock the main valve in its open position.

From the foregoing description it will be seen that not only may thevolume of Water discharged at either side be indipendently regulated,but also that the discharge may be entirely cut off either by operatingboth regulating-valves or by closing the main valve. Moreover, thepressure of the water may be controlled by adjusting the main valve andthe discharge may be regulated by adjusting the Width of the slots. Eachof the regulating-valves swings through an arc of about ninety degrees,but they may be as much longer as may be necessary to overlie theirrespective slots throughout the entire length thereof. For example, thevalve 42 extends through an arc of about two hundred and seventydegrees, although only about ninety degrees of its slot is operative,the greater part of the valve serving to close permanently that part ofits slot which is not intended to be operative I wish it to beunderstood generally that my invention is not restricted to the specificdetails of the construction described, except in so far as they areparticularly claimed, as my invention includes the use of mechanicalequivalents for the different elements of the combinations claimed.
